To all whom it may concern.

Be'it known that I, KAY FRnDRIcK ELLE GARD, a citizen of the United States, anda resident of Hartford, in the county ofHartford and State of Connecticut, have in-L vented a new 'andImproved Intern'aLGombustion Engine, of which the following-1s a' specificati'on.

this type, ofsimple construction, and that shall be particularly efficient in operation. One form of engine embodying .1 my'invention and in the construction and:;use of'which the objects herein set out',';as 'wellr asothers, may be attained, 'is illustrated in the'accompanying drawings, in which+ Figure 1 is .a view partially in side 'elevation and partially in central vertical'sec-l tion through the upper part of anfengine u l I embodylng my I invention.

In the accompanying drawings the numer-' al 5 indicates a portion er a'cr ank case of an engine, 6 a cylinder secured thereto and, rising therefrom,7 a piston located in the cylinder, and operating upon the driving rod or'pitman 8, and 9a spark plug, all

Ring packings 30 of any preferred form V are located between the inner surface of each valve and the outer surface of the cylinder, and spring pressed packings 31 are located between the inner surfaces of. the valve and the outer surface of-the cylinder on opposite sides of the ports through the valves, said" spring pressed vpackings being located in recesses 32 preferably formed; as to aportion of each recess both- .in the outer surface of the .cylinder and the innersurface ofthe valve. 'Theserspring pressed packings prevent the escape of pressure in a direction circumferentially of the f cylinder, and the ring packings, as will be readily understood, prevent the escape of pressure lengthwise of the valve and cylinders.

The connecting rods 26 pass through guides 33 in the division wall between the crank case and the chambers 24: whereby such rodsare securely held against any lat eral play and a steady movement is imparted thereby to the slide valves. An oil inlet pipe 34 may be employed asameans for supplying oil to the bail bearings. A shim or shims 35 may be inserted between the members of thejacket 10 as a means for adjusting the jacket to the requirements ofthe valves 16 and to thereby retain the valves against undue looseness. This provides an extremely convenient .means for taking up wear with respect to'the valves, as it is nec- V essary only to removea shim or shims for this purpose and the furnishing of new valves is thereby obviated. 7
